Braden Scale for Predicting Sore Risk: | Sensory Preception, Moisture, Activity, Mobility, Nutrition, and Friction/Shear |
Primary Intention | A wound with little or no tissue loss, like a clean incision - edges can come together (approximate) |
Secondary Intention | A wound with tissue loss like a laceration, pressure ulcer or burns - since the edges cannot come together. |
Delayed primary dosure | gaping wounds that closed from the inside out. |
Granulation tissue | Soft, pink, fleshy projections of tissue that form during the healing process in a wound not healing by primary intention. |
Inflammatory Response | Erythema and edema are the first response. |
Epidermal Repair | They begin migration across the wound, originating from the epidermal cells on the edges. |
Dermal Repair | Epidermis thickens, anchors to adjacent cells and resumes normal function. |
The first phase in the imflammatory phase | Hemostasis |
Proliferative Phase | new tissue, epithelialization, and contraction |
